Description

Traffic information providing system and method capable of supporting two-way data service and traffic information providing terminal {TRAFFIC INFORMATION SYSTEM, METHOD AND APPARATUS SUPPORTING INTERATIVE DATA SERVICE}

The present invention relates to a traffic information providing system capable of supporting two-way data service, a traffic information providing terminal, and a method thereof.

The navigation system is a system that provides information for driving a vehicle such as a vehicle by using a satellite and is also called an automatic navigation system.

The navigation system receives a predetermined data from a GPS satellite floating on the earth using a global positioning system (GPS) receiver, and calculates its position based on the received data.

There are a number of GPS satellites on the earth, and the vehicle can receive GPS signals from three GPS satellites in any region of the earth and based on the GPS signals received from the three GPS satellites. The position can be calculated.

Navigation system (Navigation System) provides users with a variety of driving information based on the calculated position information of the user, which was used mainly for the calculation and navigation of large moving objects, such as aircraft and ships, but in recent years widely used in automobiles, etc. It is used.

In addition to the basic navigation functions, the navigation system provides the driver with various information necessary for driving such as the direction of travel of the transport device, the distance to the destination, the current moving speed, the route set before the driver and the optimum route to the destination. do.

A general navigation system terminal measures a current location, and when a waypoint and a destination are input, searches for a route including the waypoint and a destination by a preset route searching method, and displays the searched route by matching the map data. And, the road guidance is performed along the path.

By the way, the route search method generally includes' shortest route search ',' national priority route search ', and highway priority route search', but these simple route search methods do not reflect the traffic conditions of the road, It does not reflect the road situation in the congestion / delay section that occurs during a certain period of time or due to accidents, natural disasters, etc.

Meanwhile, in order to solve the above problems, recent navigation systems provide a route search function that reflects traffic information. In general, a method for reflecting the traffic information includes a method of receiving traffic information through a mobile communication network such as CodeDivision Multiple Access (CDMA). In this case, a navigation system terminal and a mobile communication terminal are used. Since there is a configuration that can be connected or provided with a mobile communication module in the navigation system (Navigation System) to access the mobile communication network to receive traffic information, there is a problem in that a separate communication fee and information usage fee must be paid for each use.

There is a method of receiving traffic information by using a Data Radio Channel (DARC) using a frequency modulation (FM) method. This method requires additional traffic information receivers, so additional costs are incurred. There is a problem.

In addition, by installing a system using a beacon signal at the intersection of each road, it is possible to provide traffic information of the road in real time to a vehicle equipped with a navigation system, in which case the beacon has a fixed coordinate value. It can transmit accurate location signals and periodically send traffic signals such as blocked roads, roads under construction, and traffic accidents, while installing a large number of beacons to cover large areas. There is a problem that requires astronomical costs.

The present invention was developed to improve the problems of the existing navigation system that does not reflect the road traffic information, an object of the present invention is to receive the BIFS data including the road traffic information provided by the BIFS server to cope with traffic jams, etc. In addition, the present invention provides an intelligent traffic information providing system and method capable of supporting interactive services by reflecting real-time road traffic information, and a traffic information providing terminal.
